Does The Toilet Flange Need to Be Bolted? Here’s The Answer

The proper installation of the toilet flange is really important for your toilet. And that is where the bolting of it comes.

A lot of people are not aware of if they should or not do it. And that is where the confusion of it arrives.

Does the toilet flange need to be bolted?

Yes, the toilet flange must be bolted when you install it. It does not matter if you install it for the first time or replace it. You must bolt it up to the outflow pipe when installing the flange. In case you don’t do it, you will face consequences that you would not expect. Dirt may come out anytime.

You can see that this is just a brief summary of the main part. But if you continue reading, you will come across every detail you need about it.

You just need to get started now!

Do I Need to Bolt up The Toilet Flange?

To get a very straightforward answer, it is a yes! Yes, you need to bolt up the toilet flange that you would install. 

In fact, it is one of the most essential parts of the toilet flange installation. Whether you install it for the first time or replace a toilet flange, it is important.

When you attach the toilet flange to the toilet floor, you bolt it up. In case you do not do it, you have to face a few unexpected consequences. 

The main problem you would face is dirt getting out of the outflow pipe. This may happen because the unbolted toilet flange could break down at any time. 

And cracking could be very normal even if it does not break. Thus, bolting the toilet flange is something very necessary. 

Remember one thing about the toilet flange. Sometimes, the toilet flange can get rusted over time. And people replace them afterward. 

But when people replace the toilet flange, they often forget or overlook bolting it. And that is where the problem arrives. 

Thus, they come up with the issue of not bolting the toilet flange. A common issue for this could be the toilet flange getting higher than the floor.

How Do I Bolt The Toilet Flange Myself?

Bolting up the toilet flange is simple just like bolting other daily things. Although bolting the toilet flange sounds a bit complex, it actually is not.

Today, I tried discussing the bolting part of the toilet flange elaborately. So that you can do it just like a pro does it! Take a look to get started.

Step 1: Get The Right Toilet Flange

You can just not start bolting the toilet flange unless you get the right one. Thus, you must make sure that you get the right one for your toilet.

Take all the necessary measurements that you need to get the right toilet flange. In case you do not know about it properly, you can take a picture of it.

But to be even more accurate, you can measure the diameter of the outflow pipe. Or else, you may also take your old toilet flange to the store.

Whatever you do, you just have to ensure the right flange dimensions. Once you get the right toilet flange, you get started bolting it.

Step 2: Take off The Existing Nuts And Bolts

At first, you need to take off any nuts and bolts in the existing flange. Once you do it, let it rest for a few minutes. Let a bit of air pass through the holes and linings.

This helps any little dirt or dust particles to go away. 

Step 3: Bolt Up The Toilet Flange

Now, you can finally get started bolting up your toilet flange. Remember that this might take a bit of time. And you must be very careful and patient to go slow in this step.

This time you take the bolts and put them inside the holes. Just put them in one by one gradually. 

Do not go too fast as you may drop the bolts into the pipe. And then you would lose them and need to get new ones.

Step 4: Put in The Nuts

Once you put all the bolts properly, take the nuts. The nuts go in both the ways of each and every bolt. Take one to the one and another one to the other end of the bolt.

This is how you put the nuts in all the bolts that you put in. And then you would need a socket wrench to tighten up the nuts.

And remember one thing about getting a wrench. That is, it is a must to verify the right size of the socket wrench. Because if you can not do it, you can not proceed to work.

Now, you might actually be wondering where and how to get an ideal wrench for this.

But do not worry! Because I can help you out with this too. Take a look:

Once you get an ideal socket wrench, you have to tighten the nuts. Do it one by one until you finish tightening up all of them.

And finally, you would be done bolting your toilet flange successfully. This is how you can do it yourself like a professional without any pro assistance.

Once you finish it, you can then finish the toilet flange installation. Because this step being done is almost the conclusion of the installation.

Can I Hire A Professional to Get My Toilet Flange Bolted?

Yes, you can hire a professional to get your toilet flange bolted if you want. It is nothing unusual actually. But it is something that you need to reconsider actually.

Because you may not have an idea about the cost of hiring a pro for this. You know a plumber may charge a lot fixing the households.

And installing a toilet flange or anything related to it is not cheap either. You need to consider a good budget if you think of hiring a pro for this.

But a perk of hiring a pro for this is that you get it done professionally. Like, you do not have to think of what and how to do things.

A Few Helpful Tips on Toilet Flange Installation

Remember you need to go through a number of steps in the toilet flange installation. And you can not overlook the primary one to do the second one first.

Here, I tried providing a couple of tips for you.

Tip 1: Use Multiple Wax Rings

Using multiple wax rings in your toilet flange installation can be helpful. If you wonder how then here is the answer.

Your toilet flange would be more secure using multiple wax rings. Thus, you may consider using multiple rings.

Tip 2: Work on Other Departments

If you have any more issues with the toilet, you can fix it now. Look around if you do not have any issues like replacing toilet bolts. Because this would be a better time to fix it.

That is because it would be more efficient this time.

Tip 3: Keep Your Water System Turned off

When you work with water appliances, you must turn off the water system. This is always a good idea to turn off the main water system. Because it can prevent you from any watery mess.

These are the tips that might come in handy for you.


Can I use the old bolts and nuts if I replace the toilet flange?

Yes, you can use the old bolts and nuts while replacing the toilet flange. But it is not a must to do so. In fact, if you want then you may just use the new ones in the replacement. This is because you get fresh and new bolts to use for this.

Do I attach the toilet flange inside or outside?

You must attach the toilet flange inside. The toilet flange goes to the inside of the outflow pipe. And you need to connect and bolt it up accordingly. This expands inside the outflow pipe. You must not anyway leave the part of your toilet flange outside the outflow pipe.

Do I need to replace the toilet flange within months if not bolted?

Yes, you may need to replace the toilet flange if not bolted properly. This is because you know that you may go through consequences due to this. You wouldn’t definitely try to use a toilet flange which is making the place dirty. Thus, replacing it to fix it would be obvious then.

The Final Words

Now you know, does the toilet flange need to be bolted or not! I hope the info I covered here is enough for your concern!

And here is a concluding tip for you. That is, consider oiling the bolts mildly before you use them. This would let out dirt off the bolts if any. And this would be better for the bolts to be even tighter.

Good luck to you!
